Line Density Memory clog

I recently used the Line Density tool and accidentally entered an impractical output cell size. The output fuction maxed out my system resources and ArcMap crashed, leaving my hard drive clogged with what I assume are temp files.

I've tried locating these files so I can delete them, but have not been successful. Does anyone know where in the system ArcGIS stores these incomplete files, or are there other potential solutions to this problem?
